Can I play latest games in this PC?

Hi everybody, if I'm posting this in wrong category I'm so sorry! but I only got 2 days to choose if I want to buy this pc or not.
It has this info:

Acer aspire M3641
Intel® Core™2 Quad Processor Q6600 Series @ ( 4 x 2.4GHz )
Ram Memory : 4 GB ( 2 x 2GB)
HDD : 320 GB SATA
ZOTAC nvidia GeForce CUDA GT 430 - 1GB

So please whoever knows (for sure) if I can play "ALMOST" latest games.
example: GTA IV , Need for Speed: The Run , or assassin's creed 2 or Call of Duty: Modern Warfare 3 , Battlefield 3 or even GTA V

For gaming, you will want a little more power in the graphics card.

I have a 20" monitor with 1600x900 for resolution and a GeForce GTS 450. I've noticed a little lag when playing at standard resolution (no anti-alias) on less demanding games.

But is there anybody could tell me if they will work or not .... pls.

You'll be able to play games on that build, but the ones you listed will only perform well on medium to low settings. As Clifford mentioned, if you want to run these games at higher resolutions you're going to need a more powerful graphics card.

Sorry to agree with them. I recommend u to buy a custom pc with the money of this pc

No way you'll be able to play BF3 or GTA. The other games you can play on low settings but it's not going to be a great experience.

What's your budget anyway? If you build your own PC you might be able to do better.
